But Mayor de Blasio said he was confident Arnold would be cuffed again soon.

"I've been briefed on this several times, and I am absolutely convinced he'll be found," de Blasio said Monday. "They have a lot of information on this individual. I don't think it'll be that much longer."

Cops were walking Arnold from the 32nd Precinct stationhouse to a vehicle for a trip to Manhattan Criminal Court when he made a break for it, police said.

The uniformed cops gave chase but couldn't keep up. The NYPD said neither cop was facing disciplinary charges.
